Fix EAGAIN check in smb2_read_data

[LoveMHz]

GNU defines EAGAIN and EWOULDBLOCK as the same value but notes both values should be checked for portability.

This resolves a Read from socket failed issue introduced when building with non-GNU environments that define EAGAIN and EWOULDBLOCK as separate, distinct values.

As noted in the GNU libc documentation under 2.2 Error Codes.

Portability Note: In many older Unix systems, this condition was indicated by EWOULDBLOCK, which was a distinct error code different from EAGAIN. To make your program portable, you should check for both codes and treat them the same.

This patch corrects the check in smb2_read_data that could fail under a read_more_data goto and a socket read that returns EWOULDBLOCK.

Similar checks already appear in the libsmb2 codebase.

I noticed that when i was compiling on nintendo switch to test on some tests that i did, So it´s aprovable.
