filesystem: workaround bug in xfs_info, use xfs_growfs instead (#25703)

Browse source 
xfs_info is a bash script located in /usr/sbin/ (/sbin is a symlink to
/usr/sbin/) which calls xfs_growfs command. When neither /sbin nor
/usr/sbin are in the PATH environment variable, filesystem module is able to
call xfs_info because /sbin path is hardcoded in get_bin_path method, then
xfs_growfs isn't found because neither /sbin nor /usr/sbin are in the
PATH environment variable.

"xfs_growfs -n" could be used directly instead of xfs_info, the man page
states that: "xfs_info is equivalent to invoking xfs_growfs with the -n
option".

Fixes #24823.
