Caleb Sander 6f9a71c611 nvme: remove redundant status mask
In nvme_get_error_status_str(), the status code is already masked
with 0x7ff at the beginning of the function.
Don't bother masking it again when indexing nvme_statuses.

Caleb Sander 4b6821940e nvme: return string as char *, not unsigned char *
The functions in drivers/nvme/host/constants.c returning human-readable
status and opcode strings currently use type "const unsigned char *".
Typically string constants use type "const char *",
so remove "unsigned" from the return types.
This is a purely cosmetic change to clarify that the functions
return text strings instead of an array of bytes, for example.

Christoph Hellwig 354201c53e nvme: add support for TP4084 - Time-to-Ready Enhancements
Add support for using longer timeouts during controller initialization
and letting the controller come up with namespaces that are not ready
for I/O yet.  We skip these not ready namespaces during scanning and
only bring them online once anoter scan is kicked off by the AEN that
is set when the NRDY bit gets set in the  I/O Command Set Independent
Identify Namespace Data Structure.   This asynchronous probing avoids
blocking the kernel boot when controllers take a very long time to
recover after unclean shutdowns (up to minutes).
